Struct FemtoVGRenderer

Source
pub struct FemtoVGRenderer { /* private fields */ }
Expand description

Use the FemtoVG renderer when implementing a custom Slint platform where you deliver events to Slint and want the scene to be rendered using OpenGL. The rendering is done using the FemtoVG library.

Implementations§

Source§

impl FemtoVGRenderer

Source

pub fn new( opengl_context: impl OpenGLInterface + 'static, ) -> Result<Self, PlatformError>

Creates a new renderer that renders using OpenGL. An implementation of the OpenGLInterface trait needs to supplied.

Source

pub fn render(&self) -> Result<(), PlatformError>

Render the scene using OpenGL.
